Cosmic bubble and domain wall instabilities I: parametric amplification of linear fluctuations
@article{Braden2014CosmicBA, title={Cosmic bubble and domain wall instabilities I: parametric amplification of linear fluctuations}, author={Jonathan Braden and J. Richard Bond and Laura Mersini-Houghton}, journal={arXiv: High Energy Physics - Theory}, year={2014} }
This is the first paper in a series where we study collisions of nucleated bubbles taking into account the effects of small initial (quantum) fluctuations in a fully 3+1-dimensional setting. In this paper, we consider the evolution of linear fluctuations around highly symmetric though inhomogeneous backgrounds. We demonstrate that a large degree of asymmetry develops over time from tiny fluctuations superposed upon planar and SO(2,1) symmetric backgrounds. These fluctuations arise from zero…

We investigate the nonlinear dynamics of cold atom systems that can in princi- ple serve as quantum simulators of false vacuum decay. The analog false vacuum manifests as a metastable…

A covariant quantum theory of fluctuations on vacuum domain walls and strings is developed, which considers straight strings and planar walls in flat space, true vacuum bubbles nucleating in false vacuum, and strings and walls nucleating during inflation.
